The sum of RTT\/2 and the processing delay is an estimate of tranfer delay for a user plane packet from GTP-U sender's ingress to the next hop GTP-U receiver ingress. A GTP-U sender informs a GTP-U receiver about the estimated accumulated delay for a user plane path be sending an estimated accumulated packet delay that is a sum of RTT\/2, GTP-U sender's processing delay and received value of estimated accumulated delay from an upstream GTP-U sender. Thus an estimated accumulated packet delay received by GTP-U receiver represents time elapsed since a user plane packet entered 3GPP domain. A GTP-U receiver may use QoS requirement (i.e. required end-to-end PDB) of QoS flow and an estimated accumulated packet delay for User plane processing prioritization Scheduling of user plane QoS monitoring (i.e. GTP-U entity may notify that an estimated accumulated packet delay exceeds an end-to-end PDB requirement.","secretary_remarks":"Merged into S2-1902858","agenda_item_sort_order":42,"ainumber":"6.","ainame":"Enhancement of URLLC supporting in 5GC (5G_URLLC)","tdoc_agenda_sort_order":21280,"status":"merged","reservation_date":"2019-02-19 10:47:43","uploaded":"2019-02-19 13:39:38","revisionof":"","revisedto":"","release":"Rel-16","crspec":23.725,"crspecversion":"16.0.0","workitem":[{"winame":"5G_URLLC"}],"crnumber":30.0,"crrevision":"","crcategory":"B","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/tsg_sa\/WG2_Arch\/TSGS2_131_Tenerife\/Docs\/S2-1902074.zip","group":"S2","meeting":"S2-131","year":2019,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},

Proposal #1: Using the sampled actual service packets as the monitoring packet in the QoS Monitoring solution. Proposal #2: The UL\/DL packet delay between UE and PSA UPF for per UE per QoS Flow are divided to the UL\/DL packet delay between UE and RAN and the UL\/DL packet delay between RAN and PSA UPF. The measurement mechanism for the UL\/DL packet delay of Uu interface depends on RAN decision, and RAN provides the UL\/DL packet delay result of Uu interface to the UPF via N3 interface. The PSA UPF calculates the UL\/DL packet delay between UE and UPF as the sum of i) the packet delay measurement result of Uu interface and ii) the packet delay of N3 (and possibly N9) interface. Proposal #3: The PCC framework is enhanced to activate or deactivate the QoS Monitoring for the QoS Flow. Changes in Rev1: Reference to solution 19 agreed at last meeting is added in the conclusion part. Conclude that the UE is activated to initiate packet delay measurement based on the instruction received from the RAN. Changes in Rev2: Revert the addition of the description on UE side in Rev1, and clarify that RAN node initiates the packet delay measurement of UL\/DL packet delay on Uu interface, based on the QoS Monitoring policy received from the SMF. Solution #X (Accumulated packet delay estimation for QoS monitoring and division of PDB) is also concluded for normative work. Changes in Rev3: Clarify that the QoS Monitoring can be performed on different granularities, i.e. per QoS Flow per UE level, or per node level, subject to the operators' configuration, and\/or 3rd party application request, and\/or PCF policy control. Accordingly, two alternative solutions are concluded.","secretary_remarks":"Revision of S2-1902741. Agreed in parallel session.

Specifically, this contribution introduces 23.501 text to support the TSC QoS RAN WG2 sent us a LS (S2-1902723), stated the following: Considering the deterministic nature of TSN traffic, RAN WG2 has agreed that the knowledge of TSN traffic pattern is useful for the gNB to allow it to more efficiently schedule traffic either via Configured Grants, Semi-Persistent Scheduling or with dynamic grants. Therefore, it would be beneficial for the gNB to receive from the Core Network the following assistance information describing TSN traffic flow, e.g. upon QoS flow establishment: message periodicity message size message arrival time at gNB (DL) and UE (UL)","secretary_remarks":"Revision of S2-1902829.

In solution 8, the 5GS appears as a TSN bridge, and 'Applications request QoS properties that the 5G system then meets using 5G framework such as QoS Flow type (GBR, delay critical GBR), 5QI, ARP, etc.' '5GS QoS framework is reused with enhancements, if needed, in order to support time sensitive communication.' 'Evaluate the need for new QoS parameter(s) to support time sensitive communication scheduled transmission in 5GS.' Hold and Forward Buffer: In TSN networks, bridges have gate schedules that specify precise times (sub-millisecond accuracy) when frames for periodic deterministic traffic are transmitted. Burst transmission prior to or after the proscribed time window is not permitted. N6 egress at the UPF and N60 egress at the UE must adhere to these schedules if the 5GS is to participate transparently as a bridge in a TSN network as adopted in the TR23.734 conclusion (Solution 8). To compensate for jitter in transmission of frames between the UE and UPF, where TSN gate scheduling is not possible or not required, a Hold and Forward Buffer (HFB) is introduced. The HFB ensures that packets sent over N6 and N60 can be time-gated for TSC QoS flows according to IEEE protocols. This contribution proposes enhancements to support periodic, deterministic TSN traffic. Specifically, 23.501 text is introduced to support of Hold & Forward buffers for de-jittering in the UE\/UPF.","secretary_remarks":"Revision of S2-1902832, merging S2-1902074.
